Hex Head Self Drilling Screws for Light Section Steel

This 4.8mm x 16mm hex head self drilling screw is a compact, smaller-diameter option well suited to lighter roofing sheet fixings where a slim, neat fixing is preferred. The short 16mm length makes it ideal for thin sheet-to-steel connections, and no pre-drilling is required, keeping the job moving quickly. A hex head with integral washer provides a spread clamping load for a secure fixing, and the coarse thread ensures good engagement in light gauge steel. Zinc plating delivers reliable corrosion resistance for external applications. Supplied in a generous pack of 1,000 — ideal for larger roofing projects.
